AstroShield II reflective insulation is designed with two layers of heavy-duty polyethylene air-bubble film sandwiched between two highly reflective surfaces that block as much as 94% of radiant heat. These bubbles form trapped air spaces between the metalized surfaces to give the structure excellent R-values. AstroShield is a great choice for your insulation requirements and its ability to reflect heat also works well to enhance your current insulation assembly. AstroShield's surfaces reflect heat in both directions, keeping you warmer in the winter and cooler in summer.
